To tion of my invention illustrating the parts asinsure positivelocking of the two movable sembled in the formation of one or more sidemembers in proper position, I provide bricks.

placed within the mold and the top member 25 is swung upon its pivots 26mounted in the cars 27 secured to the back of the side member 5 bygrasping the handle members 28. A treadle 29 is provided which has itslegs 30 pivoted to the frame 1 at 31 and which is held normally in itsupward position through the instrumentality of oppositely disposedsprings 31 secured to the lugs 32 of the legs of the treadle and to theframe, as clearly shown in Figs. 1 and 2. The legs 30 of the treadleeach has a series of perforations 33 whereby the leverage action of thetreadle may be adjusted. The top facing member 25 is provided with a lug34 at each end formed for the purpose of cooperating with the lockinglevers 35 pivoted at their lower ends to the leg portions 30 of thetreadle, as indicated at 36. Each locking lever 35 is provided with acurved slot 37 each adapted to work upon a fixed pin 38 mounted in thelugs 39 of the frame. Thus when the top plate 25 is thrown downwardlyover the mold, the locking levers 35 present their hook portions 40 overthe aforesaid projections 34 to pull the top member 25 down tightly uponthe mold to lock the top member and to compress the material in themold, as clearly shown in Fig. 1.

When it is desired to remove the blocks or bricks from the mold, thefoot is removed from the treadle 30 when the springs 31 will cause thetreadle to move u wardly and the hook portions 40 of the locking levers35 disengage from the projections 34 of the top of During this movementneither the side 12 nor the partition members 7 of the mold are movedfrom their normal operating position. The operating handle 23 isthengrasped and moved upwardly and in its upward movement engages the handleportions 28 of the top member 25 of the mold to lift the latter upon itspivots 26 from over the mold, such operation of the operating handle 23lifting the top member and also effecting a dropping of the side member12 of the mold and the withdrawal of the partition members 7, as shownin Figs. 2 and 4. The top member 25 is limited in its backward swingingmovement by engagement with the stops 41.

.From the foregoing it will be seen that I provide a comparativelysimple and inexpensive molding machine which, in addition to itscomparative simplicity and inexpensiveness, embodies a positiveoperation and durability, the leverage connections being so proportionedas to effect these characteristics and to cooperate with means wherebythe various movable parts of the mold may be firmly locked againstaccidental displacement during the compression of the material in themold. Obviously the slits ofthe fixed side member may be spaced agreater or less distance than shown, or some may be spaced a greater orless distance from one slit than others, whereby blocks of differentsizes may be formed at the same time.
